You can realistically only really have a single Ubuntu install per system anyway, otherwise it's mad ping-pong between bootloaders overriding each other (because there can only be one "ubuntu" bootloader). And newer bootloaders might not load older kernels or vice versa. OK, OK, what I say is valid only for EFI, but well, not much point doing much more work on os-prober for nicer BIOS support (and we need to kill it on UEFI anyway, and set BootNext from grub and use entry names from UEFI BootOrder, so that each foreign OS gets booted by rebooting to it, so that measurements and secure boot chain is correct).
